The windows driver takes one sample at the previous register settings and then changes some registers before resamping (and getting much better images). The exact changes that it makes seem to vary, perhaps based on the histogram. Anyway, this is an approximation of the settings used for the 2nd sample which should help matching results.
libfprint ========= libfprint is part of the fprint project: http://www.reactivated.net/fprint libfprint was originally developed as part of an academic project at the University of Manchester with the aim of hiding differences between different consumer fingerprint scanners and providing a single uniform API to application developers. The ultimate goal of the fprint project is to make fingerprint scanners widely and easily usable under common Linux environments. For more information on libfprint, supported devices, API documentation, etc., see the homepage: http://www.reactivated.net/fprint/Libfprint libfprint is primarily licensed under the GNU LGPL. HOWEVER, THIS PRERELEASE VERSION INCLUDES GPL CODE FROM LIBTHINKFINGER, therefore distribution is subject to both the terms of the LGPL (see COPYING) *and* the GPL (see COPYING.GPL). At release time, I will contact libthinkfinger authors and see if they will be happy to relicense. I expect they will. libfprint includes code from NIST's NBIS software distribution: http://fingerprint.nist.gov/NBIS/index.html We include bozorth3 from the US export controlled distribution. We have determined that it is fine to ship bozorth3 in an open source project, see http://reactivated.net/fprint/US_export_control
